<p>^Hat - my S actually has the same struggle as yours-- no problem with grammar, but lots of trouble with vocab. (I was venting when I used the example of a grammar book in preschool-- not meaning to be literal.) S’s tutor says he is the opposite of most of her other students, because they get the vocab but struggle with conjugation.</p>
<p>Yes, I do live in a bilingual state, but here one can be quite insulated from people who speak other languages, depending on the neighborhood, schools, job, etc. Unless you deliberately immerse yourself in the other cultures/languages, you won’t get it by simply living here.</p>
